-SlPHQN-VALVE FOR WATER-TANKS.

SPECIFICATION forming part of Letters Patent No. 565,314, dated August4, 1896. Application filed February 6, 1896- Serial No. 578,268. (Nomodel.)

To aZZ whom it may concern.-

Be it known that I, MYRON I-I. WILoox, of the city of Ohillicothe,Livingston county, State of Missouri, have invented certain new anduseful Improvements in Siphon-Valves sectional View of a closet-tank,showing the siphon-pipe therein with my improved valve applied to saidsiphon-pipe. Fig. 2 is a side elevation of my improved siphon-valve.Fig. 3 is a front elevation thereof. Fig. 4 is a horizontal sectionalview taken approximately on the indicated line 4 4 of Fig. 2. Fig. 5 isa front elevation of a modified form of my improved siphon-valve. Fig. 6is avertical sectional view taken approximately on the inclicated line 66 of Fig. 5.

Referring by numerals to the accompanying drawings, .1 indicates thecloset-tank, the

same being provided with the usual siphonpipe 2 and the weighted. lever3, to which is secured the operating-chain 4.

Tapped into the main leg of the siphon-pipe at a point just below theturn at the upper end of said pipe is the valve-cylinder 5, to one sideof the outer end of which is formed integral a laterally-projecting arm6. Formed in the front face of the valve-cylinder 5 is an annular groove7, in which is seated a packing-ring 8 of rubber, leather, or analogousmaterial, the same projecting a slight distance beyond the face of saidvalve-cylinder.

Tapped into the end of the arm 6 is a screw or pin 9, to which ispivoted one end of alink 10. To the free end of said link 10 is hinged aplate 11, approximately circular when viewed in elevation, said platebeing of such size as to completely close the end of the valve-cylinder5, there being formed integral with the side of said plate 11 oppositefrom the side which is pivoted to the link 10 a weighted lug 12,carrying a hook-eye 13.

Fixed to the under side of the forward end of the valve-cylinder 5 is arectangularly-bent stop 14, the upturned end of which extends outwardlyfrom the end of said valve-cylinder. The plate 11 normally rests uponthis stop 14 when the valve is closed.

Fixed to the top and outer end of the cylinder 5 is one end of a stop15, the same extending upwardly and outwardly from the end of thevalve-cylinder 5, said stop terminating in a hook 16. A chain 17 issecured at one end to the eye 13 and at its upper end to the weightedend of the operating-lever 3,

of the tank.

In the construction of the device shown in Fig. 5 the weighted lug 12 isdone away with and a spring 18 made use of to close the plate 11 uponthe end of the valve-cylinder, said spring passing around the screw orpin 9 and having its ends attached, one to the arm 6 and the other tothe link 10. In some forms of the valve the hinge between the link 10and the plate 11 is done away with and a ball-and-socket joint made useof between the end of the plate 11 and the arm 6.

The operation is as follows: Previous to a discharge from said tank thewater in said tank must necessarily be of such depth as to completelysubmerge the valve-cylinder 5. When the operating-chain 4 is pulled, thelever 3 will swing upon its fulcrum and the plate 11 will be swungupwardly, during which movement it rides directly upon the face of thepacking 8 in the end of said valvecylinder. During its movement the link10 and plate 11 are swinging upon the pivot-pin or screw 9, and as soonas the upper edge of the plate 11 strikes the inclined portion of thestop 15 said plate 11 will swing upon the hinge which secures it to thelink 10, and thus said plate will swing outwardly simultaneously withits upward movement. As

soon as the plate 11 leaves the mouth of the valve-cylinder 5 the waterwithin the tank will discharge through the valve-cylinder 5 anddownwardly through the siphon-pipe 2. When the pull upon the chain 4 isreleased,

the valve-plate 8 will drop to its closed position, and the waterpassing downwardly through the main leg of the siphon-pipe 2 will causea siphonic action through the upper end of said pipe and the shorter legthereof, and the water within the tank as far down as the lower end ofthe shorter leg of the pipe will bedischarged. The plate 11 normallyrests upon the packing 8 in the for-.

ward end of the valve-cylinder 5 in such a manner as to form a perfectlywater-tight joint, and this being the case there will be no leakage fromthe tank. Said plate 11 moves ofi from and onto the end of thevalvecylinder with a sliding movement, and for this reason any sedimentor deposit upon the inside face of said plate will be removed to washaway with the rush of water as said plate slides upon the flexiblepacking. When said plate is in a closed position,the water-pressuregreatly assists in causing thesame to tightly engage against thepacking.

In the foregoing description I have alluded to the valve as beinglocated upon the siphonpipe of a siphon-tank. This is but one of thepoints where my improved valve is advantageously used, it being equallyapplicable upon large water-receptacles and railwaytanks wheresiphon-pipes are not used. Its operation in such tanks or receptacleswhere siphon-pipes are not used will .be readily understood by personsfamiliar with the art to which my invention pertains.

M y improved valve is entirely automatic in its action, is self-cleaning and self-adjustable upon a packing, will not easily get out of order,and by proper manipulation said valve can be opened to any pointdesired, and in this manner the flow or discharge of water from the tankis regulated. Such a valve is easily applied for use, is inexpensive inconstruction, and where made use of there will be absolutely no leakagefrom the tank through said valve.

I claim-- 1. A valve consisting of a cylinder, a plate arranged toswingin a vertical plane and close the end of said cylinder, a guidecarried by said cylinder and designed to move said plate outwardly as itis moved upwardly.

2. In combination with the siphon-pipe of a tank, a valve-cylindertapped into the longer leg of said pipe, and a plate arranged to swingupwardly and outwardly over the open end of said valve-cylinder.

3. In combination with a siphon-pipe of a tank, a valve-cylinder tappedinto the longer leg of the pipe within the tank, a weighted platearranged to swing in a vertical plane and close the end of thevalve-cylinder, a guide carried by the valve-cylinder for causing theweighted plate to move outwardly simultaneous with its upward movement,and means for operating said weighted plate.

4. A siphon-valve for closet-tanks, constructed with a valve-cylinder, apackingring located in the face of said valve-cylinder, an arm formedintegral with and projecting laterally from the forward end of saidcylinder, stops arranged on top and on the bottom of the forward .end ofsaid cylinder, a link pivoted to the outer end of the integralarm, and aweighted circular plate hinged to the free end of the link and arrangedto close upon the packed end of the valve-cylinder.

5. A siphon-valve,constructed with a valvecylinder arranged to be fixedto the siphon pipe, an annularpacking-ring located in the forward end ofthe valve-cylinder, an arm formed integral with and projecting laterallyfrom the forward end of said cylinder, alink pivoted upon the outer endof said arm, a weighted plate hinged to the free end of the link, a stoparranged at the bottom and forward end of the valve cylinder upon whichthe weighted plate normally engages, and a guide carried by the upperforward end of the valve-cylinder, the same extending up wardly andoutwardly from said cylinder.

6. A valve consisting of the cylinder 5, the arm 6 attached to saidcylinder, the packingring 8 seated in the front face of said cylinder,the link 10 pivotally connected to said arm 6, the plate 11 hinged tothe free end of said link, the stop 14 fixed to the under side of theforward end of said cylinder and the guide-stop 15 fixed to the top andouter end of said cylinder.

In testimony whereof I affix my signature in presence of two witnesses.
